Message	Purpose is not double-post but to inform more. I had these arms (= similar design) since 4 years: http://www.twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=2290942&forum=general&dtSearch=7 And they bent too ! They are made of steel, not a problem of material here, but these arms are subject to a huge amount of stress. This is always the same shape: the rear length is longer that the front length and the bearings are shot completely (my bearings don't turn anymore). You know where does it come from ? In fact, when you install new arms you notice it before having tightened the center nuts: the arms don't only travel up and down but they also twist when the suspension is travelling. The OEM arms are allowed to twist with their rubber bushings. So, all the front adj. arms relying on the same design (Powertrix, STillen and so on ...) should have the same problem after a while. These arms should solve the problem, but at a high price: http://www.300zx.com.au/pricelists/pricelist_300zxsuspension.htm In my case, no track, normal street use. The upper arms have always been fitted correctly from the first day. I have 18", tokico illumina set to the softest, eibach springs, tension rods with pivot ball. I fitted new arms: Godspeed/Megan Racing ones (China stuff) b/c they are cheap, but I know I will do the job again soon b/c of the design. One warning, the centered part will hit the body bracket on big road bumps (mine are set with 0.5° of camber) Night and day on the first test drive ! I had even forgotten the steering wheel could be responsive and the feeling, just because the previous bearings were completely shot .....
